Progress Test 3

Although the progress test is similar in style to the unit evaluations, the progress test is a

closed-book test. It is important that you do your own work. Select the response that

best completes the statement or answers the question. Your graphing calculator may be

used on this progress test. You may also use scratch paper to work out the solutions.
